description The utility model relates to a damping device with active controlling function for internal combustion engine, and comprises a photoelectricity code disc, a single chip microcomputer, a timer, a memory, a step drive electric soure, a frequency modulation damper, etc., with making up a speed-measuring system, a control system and an executive system respectively. By the detected rotation speed signal, the single chip microcomputer can regulate and control the natural frequency of the frequency modulation damper. When an inertial body's natrual frequency in the frequency modulation damper coincides with an internal combustion engine's entire vibratory frequency, for their phase positons are oppsite, the interal combustion engine's vibratory energy is counteracted, and the purpose of tracing damping is realized. The utility model is arranged on the internal combustion engine as an accessory, with no needing to improve the internal combustion engine's structure, and can also be used for other damping required mechanical equipment directly for simple and convenient installation.
